This paper analyzes the stability of input and output quantized discrete-time linear control systems considering static finite-level logarithmic quantizers. The sector bound approach together with a relaxed stability notion are applied to derive LMI based conditions for estimating a set of initial conditions and its attractor assuming that the controller(More)
Modern networked control systems integrate multiple independent feedback control loops that require guaranteed bandwidth for timely operation. However, planning the distributed control systems considering worst-case requirements leads to expensive and inefficient designs. This motivated the development of dynamic rate adaptation as a technique to support(More)
This paper is focused on the problem of obtaining wide band transformer models for electrical power system transient simulation purposes. It is analyzed the use of orthonormal basis functions models in such context. A model structure selection strategy, based on the transformer properties, is discussed and the frequency-domain parameter estimation procedure(More)
